From cea8e2f3938c510f6041c632fe19e4e95296ae04 Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Thu, 10 Jan 2019 09:32:01 +0530 Subject: dt-bindings: opp: Introduce opp-level bindings Add opp-level as an additional property in the OPP node to describe the performance level of the device. On some SoCs (especially from Qualcomm and MediaTek) this value is communicated to a remote microprocessor by the CPU, which then takes some actions (like adjusting voltage values across various rails) based on the value passed.
